Glacier retreat, dynamics and bed overdeepenings of Parkachik Glacier, Ladakh Himalaya, India

Annals of Glaciology, 2023
This study describes the morphological and dynamic changes of Parkachik Glacier, Suru River valley, Ladakh Himalaya, India. We used medium-resolution satellite images; CORONA KH-4, Landsat and Sentinel-2A from 1971–2021, and field surveys between 2015 ...

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Climatic control on seasonal variations in mountain glacier surface velocity

The Cryosphere, 2023
Abstract. Accurate measurements of ice flow are essential to predict future changes in glaciers and ice caps. Glacier displacement can in principle be measured on the large scale by cross-correlation of satellite images. At weekly to monthly scales, the expected displacement is often of the same order as the noise for the commonly used satellite images,

Clathrate hydrate crystallization

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

Analyzing ice dynamics using Sentinel-1 data at the Solheimajoküll Glacier, Iceland

GIScience & Remote Sensing, 2020
The climate in southern Iceland has warmed over the last 70 years, resulting in accelerated glacier dynamics at the Solheimajoküll glacier. In this study, we compare glacier terminus locations from 1973 to 2018, to changes in climate across the study ...

Image analysis techniques to estimate river discharge using time-lapse cameras in remote locations [PDF]

, 2015
Cameras have the potential to provide new data streams for environmental science. Improvements in image quality, power consumption and image processing algorithms mean that it is now possible to test camera-based sensing in real-world scenarios.

Remediation of Organic Pollutant for Wastewater Treatment by Employing Sustainable Graphene Oxide/NiO‐ZrO2/Zeolite Ternary Composite Material

CleanMat, EarlyView.
Graphene oxide/NiO‐ZrO2/zeolite ternary composite was synthesized hydrothermally. Efficient adsorption of Congo red onto GO/NiO‐ZrO2/zeolite composite was studied. ABSTRACT The present study employs a novel method for the synthesis of graphene oxide (GO) based ternary composite utilized for the adsorption of Congo red (CR), an anionic dye molecule. The
